Increasing Decreasing Sequence
Problem is in taking input, your code isn’t taking input properly which results in run-time error. So, you can modify your input function like this https://ide.codingblocks.com/s/151813.
Reason: your input function will work fine if input is space separated but if you’ll check the sample input, every input number is coming in a new line.
Apart from this, there is a small logical mistake in your code. Its mentioned in the problem clearly that sequence should be strictly dec or strictly inc, So, strictly means 2 equal no.s should not be present consecutively in the sequence. For this, update your if checks
if l[i-1]>=l[i]: as if l[i-1]>l[i]:
and
if l[i-1]<=l[i]: as if l[i-1]<l[i]:
I hope this will help you 
If you have any further doubt then please feel free to respond to this thread.
The only difference between your solution and my solution(regarding taking input) is that you are using insert function in the list whereas I am using append function. So was the issue just because of using the wrong function? If yes, then please describe the difference between the two.
